It's another CLAMP manga and anime. It's cute, romantic, mysterious (in that from the beginning there's questions about the protagonist) and because of this I found it to be an interesting manga, I've read 5 volumes so far.

I just finished watching the anime which although was different from the manga still managed to maintain the same charm.

Basically it starts off with Kobato, a girl, who has a wish to be somewhere and in order for this wish to come true, she must collect 'healed hearts' which in the anime they refer to as konpeito. With some guidance from Ioryogi, a being that looks like a blue stuffed dog, she sets off to fill a flask full of these konpeito.
